SPARKING IGNITER FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 727,399, dated May 5,1903.

Application filed November 23, 1901. Serial No. 83,418. (No model.)

To on whom it may concern:

Be it known that I, EMIL MAERKY, a citizen of the Republic ofSwitzerland, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Sparking Igniters for Explosive-Engines, of which the following is aspecification, reference being had therein to the accompanying drawings.

My invention relates to improvements in sparking igniters for gas orgasolene engines; and the object of my invention is the provision of asimple, inexpensive, durable, and practical device which will operatereliably and perfectly to ignite the charge of gas or gasolene.

With this object in view my invention consists of an electric igniterembodying novel features of construction and combination of parts,substantially as disclosed herein.

In order that the details of construction of my igniter may be fullyunderstood and its numerous advantages be fully appreciated, I haveillustrated in the accompanying drawings mechanism constructed inaccordance with and embodying my invention.

Figure 1 represents an end View of my igniter mechanism. Fig. 2represents a transverse sectional view of the end or head of a cylinderwith mymechanism in position therein. Fig. 3 is an .end view of myinvention, illustrating the position of the parts just before the sparkis formed.

Referringby numerals to the drawings, the numeral 1 designates the headof a cylinder which is provided with a chamber 2, in which fits the plug3, which has the wings 4 to receive the nuts 5 for securing the plug inthe chamber of the cylinder head. Passing through the plug is the pin orshaft 6, which carries at its inner end the arm 7, provided with acontact-point 8, and t0 the outer or exposed end of the shaft is securedthe oppositely-extending arm 9, which normally rests between theclamping or gripping device, which is composed of the lever 10 and theright-angled lever 11, both of which levers are mounted upon a stud 12,common to both levers, and the angle-lever has its vertical arm 11provided with an opening 11 which fits upon the curvedguide-rod 13,which de pends from the inner end of the straight or horizontal lever,and around the guide-rod is placeda coiled spring 14, which bears uponthe arm of the angle-lever and the inner end of the horizontal lever andbrings the fingers of the two levers into close engagement with the arm9 and at all times holds the said arm 9 between said fingers, and whenthe inner end of the horizontal lever is struck by the projection 15 onthe shaft 16 the clampingfingers are elevated and turn the shaft whichcarries the contact-point. Passing through the plug and parallel withthe shaft 6 is the pin 17, which carries at its inner end the contact-point 18 and at its exterior or exposed end receives the electricconnection 19 for making, with the electric connection 20, the circuitto produce the spark between the contact-points and the cylinder toignite the charge, as will be evident.

From the foregoing description, taken in connection with the drawings,the operation of my invention will be readily understood, and I willstate that the revolution of the shaft carrying the projection bringssaid proj ection at the proper time in contact with the end of thelever, which slightly lifts said 10- ver and also the clamping-fingers,which turn the arm on the outer end of the shaft, this turning of theshaft bringing the arm with the contact-point on the inner end of saidthe inner end of the rigid pin, making the circuit. When the projection15 passes out of engagement with the lever 10, the spring 14 causes saidlever to strike the arm 9, thereby separating the electrodes and cansinga spark which ignites thecharge in the cylinder, and this operation isrepeated continuously With an even and reliable action, and thespring-controlled angle-lever insures the gripping of the clamp upon thearm on the outer end of the shaft, and a reliable op eration is certain.

It is evident that I provide an igniter which is ofextremelyinexpensive, simple, and durable construction and can be easilyapplied to the cylinder-head of the engine and that is thoroughlyefficient for the intended purpose.

shaft into contact with the contact-point on ing device to hold it inproper engagement with the rock-shaft, and means for operating the leverto rock the shaft to bring the points together.

In testimony whereof I affix my signature i in presence of twoWitnesses.
